Bryan: California is a difficult place to learn, because everything is so pricy.  

My question is this - does Johnson City receive enough visitation to justify a successful STR?

I would mention to Tenant B that I was visiting Tenant A and smelled what seemed like marijuana smoke coming from their side and remind them there is no smoking permitted inside the house.

We have a relator out of Redding, CA whom we work with each time we look into real estate buys.

Now keep in mind that a LOT of people visiting my website are competitors and investors copying my site you can imagine that my conversion rate is quite high.So what you should be asking is really this.

No, DIY is not the same as a virtual site visit or a study done by engineers @Dana YobstAs @V.G Jason said, you could very likely cost yourself more in time and money.

Would appreciate any other good options, especially those with focus on California markets. 

Today this would be possible in high priced markets were your average loans are more in the 500k range so only 10 a month.. like CA  NJ  Denver and ski areas . 

what you're proposing, while possible, is incredibly difficult and highly risky, and i don't know how you would do it completely remotely with no plans to visit or set up a team.i think i've said this in other posts, but there is tremendous demand for inventory right now among both retail buyers and investors. 

Where's in CA?
